MOBILE, Ala. -- Denard Robinson wore a yellow No. 16 no-contact jersey for the second straight day because of his nagging elbow injury at the Senior Bowl, and NFL Network analyst Charles Davis said Robinson is missing a valuable chance to show NFL talent evaluators that he can make the transition from quarterback to receiver.

“I’m not sure that’s all his fault -- because he’s been dinged up, he can only do so many things,” Davis said. “I know that in one-on-one drills, they weren’t allowed to press him, they had to back off of him because of the injury he has. So no, the answer is no (he hasn’t done enough to prove he can play receiver). He’s got a long way to go with that.”

Robinson ran a handful of routes in one-on-one drills after being limited to position work Monday, but the all-time FBS leader in career rushing yards by a quarterback sat out full team drills for the second straight day.

He beat Utah State cornerback Will Davis with a nice double move to catch a deep ball in one-on-ones, but Charles Davis said Robinson is still “extremely raw” in his route running.

“That’s like taking me and saying, ‘All right, now Charles, you’ve been doing football your whole life, I want you to captain a Viking ship,’” Davis said. “It’s brand new stuff, and even though I may have some knowledge because I’ve watched movies and read a book, it doesn’t mean I’m capable of it just yet. Does it mean I can’t grow into it? No, it means I can, but he still has to do that. He’s just going to be raw early.”

Robinson, who suffered nerve damage in his right elbow in Michigan’s October loss to Nebraska that still makes it difficult to grip a football, said he hopes to be cleared for full contract in time for Wednesday’s practice.

Along with his receiver work, he continued to field punts during a special teams period at the end of practice. Robinson said he felt more comfortable in his second day catching balls from a left-footed punter, but he only made one clean catch on the four punts he fielded.

He misjudged two punts that bounced a few yards in front of him and bobbled a third.

"It takes some time with guys," Davis said. "We’re expecting him to come out right away and run every route correctly and do this, that and everything. That’s just not fair to him."
